A Novel Trusted Computing Model for Network Security Authentication

Network information poses great threats from malicious attacks due to the openness and virtuality of network structure. Traditional methods to ensure infor- mation security may fail when both integrity and source authentication for information are required. Based on the security of data broadcast channel, a novel Trusted Com- puting Model (TCM) of network security authentication is proposed to enhance the security of network information. In this model, a method of Uniform content locator security Digital Certificate (UDC), which is capable of fully and uniquely index network information, is developed. Standard of MPEG-2 Transport Streams (TS) is adopted to pack UDC data. Additionally, a UDC hashing algorithm (UHA512) is designed to compute the integrity and security of data infor- mation . Experimental results show that the proposed model is feasible and effective to network security authentication.
